Hence I do not limit myself to the precise construction and arrangement hereinabove set forth and illustrated in the accompanying drawings; but,

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A Water-heater comprising the combination with a boiler, of a heater embodying a shell having superposed hot and cold water spaces, a source of heat below the heater, a feed Water pipe passing rup through said source into the heater and connecting the boiler with the cold-Water space, nested pipes connecting the hot and cold Water spaces, and

a connection from the hot-Water space to the boiler, substantially as described.
